Magnefix MD4 iCap

Increase hosting capacity and accelerate energy transition

Maximizing the hosting capacity of existing grids is an important strategy of Distribution Network Operators (DNOs) to keep pace in the facilitation of renewable energy sources and electrification of loads. The first step in achieving this is to obtain real-time information from the network, in order to consequently make more argued decisions on available capacity and congestion problems. Since the mid-fifties last century, Eaton has been producing and delivering Ring Main Units all over the world in the form of the Magnefix MD4 installation. The extension to this installation, the Magnefix MD4 iCap, now allows the operator to monitor the ongoing current flows and detect short circuit situations. It features advanced voltage and current measurements, including precise directionality and short circuit detection capabilities. Integrating seamlessly with digital infrastructure, it offers local and remote monitoring through webserver access and Modbus communication for integration into the digital environment of the operator, ensuring optimal medium voltage grid management.

Data architecture

Specifications

The iCap system is available in two configurations:

KKKT: Cable – Cable – Cable – Transformer (fields)

KKT: Cable – Cable – Transformer (fields)

In these configurations, typically only the K (cable) fields are equipped with an iCap for each phase. Thus, the KKKT configuration contains 9 iCaps and the KKT configuration contains 6 iCaps.
